How To Daily Maintenance of The Uncoiler?
Uncoiler is a special equipment for straightening metal plates, which can be composed of flat line steel plates, not flat plates into uncoiling, leveling, cutting production lines and other plate product lines according to the relevant configuration. Applicable to machinery, vehicles, metal products home appliances, steel structures, decoration and other industries.
Roll opener is one of the essential and important equipment in the welded pipe production line, one of its functions is to support the coil by pulling the hole inside the coil tightly. The other is to send the steel strip head to the corrector through the cooperation of the straight head machine. Therefore, the performance of the uncoiler is very important to the whole production line. The continuous optimization of the uncoiler structure has been improved during years of design practice to enhance the performance of the uncoiler.
Uncoiler
The uncoiler spindle has two functions, one is to guide the coil rotation. The other is the taut support of the steel coil. The expansion is generally achieved by advancing a barrel or cylinder tilted slider mounted with the spindle, mostly using cylinders for small installations and cylinders for large installations. Rotational realization is usually accomplished by an electric motor driving the spindle through a reducer. The drum or cylinder mounted on the spindle needs to rotate with the spindle, and the drum or cylinder needs to be connected all to one end of the working medium line, and the other end of the line is connected to a hydraulic station or solenoid valve.
The uncoiler is placed in front of the entrance section of the unit corresponding to the 1,2 mini carriages respectively. One of the roles of the machine‘s opener is to raise the volume while maintaining tension after stripping, and another important role is to achieve automatic strip pairing in the CPC. The common soft rewind and color machine consists of two uncoilers, both of which take turns to uncoil, creating the prerequisites for the continuous production of the machine‘s subsequent equipment. An uncoiler is equipped in the shear line. The strip tension of the inlet section is set by the uncoiler and the 1 tension roller group of the device.
The main body of the uncoiler is a welded box-type structure. The variable speed motor drives the rolling shaft after deceleration through the gear box to provide the main power for the uncoiler. The reel of the uncoiler is a hollow shaft that supports the gear box through two bearings, between which electric spur gears are installed. The gearbox is lubricated by forced lubrication, and the closed-loop oil lubrication system is equipped with two even-speed motors. The arbor is a cantilever structure supported by external support bearings for maintaining the stiffness and stability of the opener during rolling.
What are the operating regulations of the uncoiler?
The uncoiler should strictly abide by the Operating Regulations of the uncoiler.
1. In the upper material work, someone should work with the forklift driver to keep the basic consistency between the steel coil material and the middle of the expansion roll shaft, and the forklift driver should slowly put the steel coil material on the trolley.
2. The worker should ascend or descend (lift truck) to adjust the steel coil material to the middle of the expansion roller shaft (i.e., the material can enter the expansion shaft), at this time adjust the movable bearing pad on the top of the rutting machine to keep the horizontal line (such as the rutting machine).
3. Adjust the expansion nut to make the 4 arc plates and steel coil material taut to prevent the deformation and damage of the steel coil material during the work.
4. After the steel coil material expands, turn the roll opener by hand to observe whether the material turns freely to avoid various hidden problems in work.
How to daily maintenance of the uncoiler?
In order to make the life of the opening machine longer, we have to carry out daily maintenance carefully, as follows
1. Grease each oil cup lubrication and manual lubrication point as needed.
2. According to the parameters specified in the opener, the thickness of the coil and roll is 20 mm, the length of the large is 2500 mm, and the yield limit of the roll material is less than 250Mpa.
3. After opening the machine, carry out the two directions of the lower roller front and rear and the upper roller rising movement, check whether each movement has the normal card death phenomenon.
4. Strictly follow the open roller machine coil processing procedure and operation method to operate, and pay high attention to the operation of the equipment when the top roller rises to the limit position.
5. Only after the main drive is stopped, the top roller can be lifted and the tilting of the overturned bearing reset and the top roller.
6. If irregular noise, impact and other abnormalities are found during operation, stoppage should be carried out immediately for inspection.
7. operation, the personnel should coordinate with each other, listen to the authorized person in charge of the command, no oral orders, prohibit the machine start.
8. When using the uncoiler reel, pay great attention to the hand is pressed by the steel plate and rolled in together with the steel plate.
9. Please be careful not to collide with the machine when driving and lifting the steel plate or reel.
After the work of the uncoiler is finished, clean up the site after the project, do a good job of equipment maintenance, and shut down the machine in time.
